Pregnant Mothers Taking Prenatal Folic Acid May Not Help Boost Sons' Fertility
Young men whose mothers took folic acid supplements while pregnant did not grow up to produce healthier sperm, a small Danish study has found. The research, published in the journal Fertility and Sterility, was the first to compare the quality of sperm from sons of mothers-to-be who took folic acid with sperm from men whose mothers did not take the B vitamin. Because the study was small, however, other researchers say they view the results with caution.
